2027 Crabgrass Germination Forecast: 401 US Metros

Crabgrass seeds germinate once soil temperature holds 55°F for a few consecutive days— and pre-emergent only works if it's down first. We computed the typical crossing date for 401 metros from ten years of daily soil-temperature data (2016–2025). Nationally it spans Jan 1 (Boca Raton, FL) to Jun 2 (Anchorage, AK) — a three-month spread that calendar advice ignores.

How to use it: find your metro, put pre-emergent down by the apply-bydate (two weeks before the typical crossing), and remember the range column — springs vary by weeks, so the safest play is watching your own ZIP's live soil temperature.

Methodology

For each metro we geocoded the central ZIP (zippopotam.us), pulled daily mean 0–7 cm soil temperature for 2016–2025 from the ERA5 reanalysis via the Open-Meteo historical weather API (weather data by Open-Meteo, CC BY 4.0), and recorded each spring's first date where soil held at or above 55°F for five consecutive days — the same sustained-warmth convention used by turf-science germination trackers. The forecast date is the median across the ten springs; the range shows the earliest and latest crossings observed. "Year-round risk" metros (Gulf Coast, southern Florida, desert Southwest) typically never cool below the trigger for long.

A median is a planning tool, not a guarantee — an early spring can move your real window up two weeks or more. Each metro links to its live soil-temperature tracker, and this table is free to cite or republish with a link to this page (CC BY 4.0). Questions or a metro we should add: hello@lawntide.com.

Don't babysit a table.

We watch your ZIP's soil temperature all year and email you the week each treatment window opens — free.
